.y TALKINQMACSIWE HORN.

i i l i' thereof, and -has for its object the provision of a talking macliiriehorn so constructed as to eliminate the metallic jangling and clatter caused by the'vibration of the metallic horns commonly used.

' i", the provision of a horn or amplifier consist- .i ing of an inner section of fibrous non-metall lic material, an outer section of fabric, and a coating of adhesive holding the inner and outer sections together.

A further object is the provision of a horn 1 4of this character which may be either oi .the exposed type or of the type used in talking machines of the cabinet style, the construcl 25 tion o the Ahorn being the same in'either f instance and being such as to atlord proper resonance While avoiding any metallic tones. A further object is the provision of a horn of this character which will be very simple and inexpensive in manufacture, highly eu l cient and durablein use, and a general improvement in the art. n With the above and other i vantages in view, the invention consists in 3? the details of'construction to be hereinafter j. more fully described and claimed, and illus- ,3 trated in the accompanying drawing, in 'l which- Figure 1 is a longitudinal sectional view 4Q'through a talking machine of the cabinet ty e'showingthe horn iii side elevation, l ig. 2 is a cross sectional View through the talking machine showing the horn in end l elevation, l

arm B communicates with the siiiall end C of :i tone horn D. The construction of the talking niucliine itself forms no part of the present invention though certain parts thereot are shown for the sake of illustration.

My invention resides in the construction of the. horn D. Iii carrying out my inven- A tion I foi-in the horn D of an inner section l() of non-metallic material, preferably paper, card-board, or papier mch, which may be pressed or otherwise formed into the proper shape. As is commoninliorns for tliis'par- 'ticular purpose, the horn D has its con- Stricted end formed cylindrical and its large.

end flllfcrmedrectangular.;V Wound upon. theinnersection l0 is a layer l2 of fabric of any suitable material and texture. This fabric might be applied in dit'erent ways and might even be cut to shape and molded upon the inner section 10, though I preerably form it from a strip 13 of suitable width wound spil-ally upon the inner sectic-n i0 with the edges of euch convolution in overlapping relation to the preceding convolution, as clearly shown in the drawings.' If desired, the inner section 10 may be coated with adhesive before the strip 13 is 'Wound thereupon, and after the strip 13 has been applied a coatinff ot sliellac is applied to the exterior thereoi. Even though no adhesive be used before the fabric is applied, the coating of shellac applied exteriorly to the fabric will soak through and hold the fabric closely onto the inner section. The

horn constructed in this manner is positioned Within a talking machine in the ordinary manner and. will perform all the iinctions of the present style of metallic horn in exactly the same manner, providing proper resonance und ampliticationlof the sounds while eliminating the disagreeable metallic tones caused by the vibration `ot a metallic horn. Actual experiment has demonstrated that a horn constructed in this manner insures the emission of a clear tone or" ample volume unaccompaniedby any distasteful clangor,

. lVhile the invention contemplated primarily the provision ot ahorn designed for use in connection with talking machines of 4the cabinet type, I intend that the old style horn of the entirely exposed type may be constructed in the same manner. In Fig. 5 I have shown a horn of this type and in'this form it is of course preferable for the sake of pleasing appearance that an additional layer li oli' paper or other similar material be applied exteriorly upon the layer of fabric so as to provide :i Smooth finish.

While l have shown and described the preferred embodiment of the invention, it-

\\'ill of course be readily under tood that I reserve the right to make slit-li changes in the details of construction, size, specific sliapeand employment of specific materials, as win not depart from the spirit of the invention nor the Scope of vthe subjoined claim.

Having thus described my invention, I claim 'v A talkin-g machine horn comprising; an in nerbody formed of fibrous material, a strip of fabric wound spirallv nnen said inner lmyAx-ith the edges of the eonvolutions in" overlapping relation to form in effect aV colitinuous layer, and an adhesive coating upplied externally upon said layer.
